Title: Improvements in and relating to electromagnetic relays
IPC: H01H50/54
Filed: 1953-04-16
Abstract: 743,012. Electromagnetic switches. GENERAL RAILWAY SIGNAL CO. April 16. 1953 [May 27, 1952], No. 10421/53. Class 38(5) An electromagnetic relay for carrying relatively heavy currents in railway signalling systems, where contact bounce or vibration is undesirable, comprises a pair of spring contact members 27, 28 biased into engagement, but movable out of engagement by a contact operator 41 carried by armature 7 and so arranged that when the contacts are closed the armature is disconnected from them. The contact member 27, 28 of which there may be several pairs, are mounted on brackets 25 carried by an insulating base plate 5. This base plate also bears two magnetic cores with polepieces 6, which cores carry energizing windings 8, the armature 7 being pivoted on trunnions 12 mounted on bracket support 9 and so spaced in relationship to the pole pieces that it moves up when the coils are energized to open the contacts by means of operator 41 and downwards under gravity and pressure of spring 20 to allow the contact to close, upon de-energization. Pins 14 determine the minimum airgap, while downward armature movement is limited by set screw 18 in a back stop member 15 carried by the base plate 5. For reducing contact bounce and vibration the contact members may have similar weights but different periods of vibration by the normal pressure between the arcuate contact 38 on member 27 and the contact button 36, which may be of silver, on member 28 is a little less than the pressure as measured at contact 36 between member 28 and limit arm 29: the centres of percussion and of gravity of member 27 are at the centre of contact 38. A modification is described in which the movable spring contact members of a multiple assembly are moved simultaneously by a pusher which engages them with lost motion to allow for the disconnection in the closed contact position, the pusher being moved by a spring-loaded armature. Figs. 3. 4 (not shown). Specification 318,916, [Class 38(v)], is referred to.

Abstract: 541,938. Condensation products. LILLEY, H. S., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 17, 1940, No. 10448. [Class 2 (iii)] Synthetic resins are prepared by heating together a phenol, an aromatic hydrocarbon carrying a vinyl group attached directly to the aromatic nucleus, and a drying or semi-drying oil. Specified phenols are phenol, p-cresol, p-tertiarybutyl phenol, and m-5-xylenol, and specified hydrocarbons are styrene and its homologues and vinyl naphthalenes. The reaction may be conducted either in the presence or absence of a volatile solvent, and in the presence of a catalyst known to accelerate the polymerization of styrene and having an acid re-action or being capable of splitting off acid, e.g. tin or silicon tetrachloride or borofluoro acetic acid. The resins may be admixed with solvents, thinners, driers; plasticizers or pigments and the resulting compositions used as varnishes. The initial re-action products may be subjected to a further heat treatment in the presence of an additional quantity of drying or semi-drying oil. In examples, styrene, phenol and either (a) tung oil and tin tetrachloride or (b) bodied linseed oil and silicon tetrachloride, are heated together with stirring, and the resulting mass is de-coloured by heating with calcium oxide and allowed to settle. The clear liquid is decanted, heated to drive off excess phenol and styrene, and more oil is added. The temperature is then increased and the heating continued until a product of the desired viscosity is obtained, which may be thinned with white spirit. Specification 456,359 is referred to.

Abstract: 1439441 Making superconductive conductors; drawing SIEMENS AG 8 March 1974 [9 March 1973] 10576/74 Headings B3A and B3P [Also in Division H1] A method of manufacturing seamless tubular conductor comprises depositing a layer of Nb 9 on a Cu layer 7 by fusion electrolysis. In a method of manufacture described, the electrolyte 5 comprising an eutectic mixture of NaF, KF and LiF in which K 2 NbF 7  has been dissolved (as disclosed in a article by Mellors and Sanderoff in "Journal of the Electrochemical Society" Vol. 112 (1965) p. 266) is introduced into the container 1 (preferably Ni) situated in the lower part of a coating chamber 2 made from high grade steel. The chamber 2 is evacuated through branch pipes 3 and 4 and then flushed with an inert gas such as argon. The electrolyte is heated to about 740 C. and melted, by the electric resistance furnace 6, before immersing the Cu tube 7 which acts as the cathode, and a coaxially disposed Nb tube which acts as the anode. A Nb layer approximately 0À6 Ám. per minute can be deposited when the current density is approximately 40 mA/cm.<SP>2</SP> at the cathode. The Cu may have, e.g. an internal diameter of 50 mm., wall thickness 20 mm. and length 500 mm., and the Nb layer may be smoothed by turning before cold drawing the composite tube, using a round bar hardened steel mandrel (11) and a hard metal or steel nozzle (13) as in Fig. 2 (not shown). Drawing oil, "Zapon" (Registered trade Mark) lacquer, or emulsion of spirit and zinc stearate may be applied as drawing aids, drawing speeds being typically about 5 m./minute. The Nb may also be coated with a layer of Nb pentoxide by anodic oxidization, e.g. in a 25% aqueous ammonia bath. Final tube dimensions are typically 10 mm. long with Cu and Nb layers approximately 1 and 0À1 mm thick respectively. The internal diameter of the tube can be reduced by, e.g. drawing over a floating mandrel.

Title: Improvements in or relating to optical viewing devices and stadiametric range finders
IPC: G03B13/06
Filed: 1944-06-02
Abstract: 581,026. Viewing devices. KODAK, Ltd. June 2, 1944, No. 10664. Convention date, June 4, 1943. [Class 97 (i)] [Also in Group XXI] An optical viewing device comprises means for viewing in a comparison plane an image of a target, a pair of reflecting surfaces intersecting to form a roof edge at an angle which is a submultiple of 360‹, a pattern-forming element or "patrix" near one end of the roof edge which, together with images thereof in the reflecting surfaces, forms a pattern, and means at the other end of the roof edge for projecting in the comparison plane a comparison image of said pattern. As shown in Fig. 1 two mirrors 38, 39 intersecting to form a roof edge reflect the image of an adjustable patrix 37 to form a pattern 42 which is projected by a lens 40 into a comparison plane 32 and is viewed through an eyepiece 33 simultaneously with an image of the object. Movement of the patrix alters the size of the comparison image and enables the known size of the target to be measured and the range indicated on a control knob 48 by a pointer 51. In a modification (Fig. 4, not shown), applied to a periscope, a warning, signal in the form of a small lamp may be incorporated in the pattern forming system. The comparison plane may be a plain sheet of glass having a dichroic surface so that the target image and the pattern may be given different colours. Figs. 14, and 15 show different forms and angles of patrix and reflectors, and the patterns they produce. Fig. 29 shows a short prism silvered at one end 243 used as a reflector which gives a working length of twice the length of the prism. The patrix is placed close to the roof edge of the exit face having sufficient area to include the maximum aperture 244, and the image is collimated by the lens 245 so that, when received in the comparison plane 246, it appears to be at infinity. Fig. 21 shows the invention applied to a reflex sight wherein an image of the patrix at infinity is projected on to a semi-reflective plate 183. Figs. 16 to 20 (not shown) illustrate different forms which the optical system may take.
